Dual-Purpose Optical Sound Prints

This paper describes a method of recording and printing two separate sound tracks within the normal single-track area for 16mm or 35mm release prints. A projector conversion kit for reproducing the double tracks separately or simultaneously is also discussed. This technique has possible application in reducing distribution costs on foreign versions and in the educational and television fields.
